Manganese Dioxide (MnO2) Supplier in Malaysia
- Also known as
- manganese(IV) Oxide
- MnO2
- Pyrolusite
- Manganese Peroxide
Manganese dioxide supplier for battery, glass, welding and water-treatment buyers in Malaysia. Also written manganese(IV) oxide and searched as MnO2, it is a black to dark brown oxide (CAS 1313-13-9) supplied as powder or granules. Assay and mesh differ sharply between ore-derived and synthetic material, so state the grade the process needs.
The traded range runs from natural pyrolusite powder through chemical manganese dioxide to electrolytic grades for alkaline and lithium cells. Coarser granular material serves as oxidising filter media for iron and manganese removal. MnO2 content, particle size and impurity limits separate these grades far more than the shared name suggests.
This page covers manganese(IV) oxide only. Manganese(II) oxide, the green-grey fertiliser, feed and metallurgical powder, is a separate product with its own page, and manganese sulphate and potassium permanganate are different manganese chemicals again. Confirm which compound the specification names before ordering.
Send the required grade, MnO2 or manganese content, particle size, quantity and delivery location with your enquiry. Availability, packing, documentation and timing are confirmed with the quotation. Supply is subject to applicable requirements.

Manganese Dioxide grades and forms
We supply several forms to suit different formulating and dosing setups. If you need a size that is not listed, ask us.
| Grade | Form | Assay | Typical use | Packing |
|---|---|---|---|---|
| Natural manganese dioxide | dark brown to black ore-derived powder or granules | — | Glass decolourising, ceramic and brick colouring, and welding-flux work where ore-derived pyrolusite at a stated MnO2 content is acceptable and battery-level purity is not required. | Bag packing for the powder or granules; the size is confirmed with the quotation. |
| Chemical manganese dioxide (CMD) | fine black synthetic powder | — | Zinc-carbon dry cells and general oxidation duty in synthesis, where a synthetic powder holds a steadier assay than ore-derived material. | Packing is confirmed with the quotation for the quantity ordered. |
| Electrolytic manganese dioxide (EMD) | fine black to grey-black powder | — | Alkaline and lithium primary cell cathode mixes, chosen for high MnO2 content, controlled crystal form and tight impurity limits. | State the preferred pack size and packing is confirmed with the quotation. |
| Activated manganese dioxide | fine activated black powder | — | Reagent-scale oxidation and adsorption duties that call for a higher surface area powder rather than a dense ore grade. | Packing options are confirmed with the quotation. |
| Filter media grade manganese dioxide | granular black media | — | Iron, manganese and hydrogen sulphide removal in water-treatment filter beds, selected on particle size and backwash behaviour rather than on battery assay. | Bagged granular media; the bag size is confirmed with the quotation. |

Common questions about manganese dioxide
Is manganese dioxide the same as manganese oxide?
No. Manganese dioxide is manganese(IV) oxide, MnO2, a black to dark brown oxide used in cells, oxidation and filter media. Material traded plainly as manganese oxide is the manganese(II) compound, a green-grey fertiliser, feed and metallurgical powder with its own page, so order that one by name.
What is the difference between natural, chemical and electrolytic manganese dioxide?
They are grades of the same compound produced by different routes. Ore-derived natural material carries a lower and more variable MnO2 content, chemical grades are synthetic powders with steadier assay, and electrolytic grades reach the highest purity and controlled crystal form for battery cathodes.
Which grade suits battery manufacture?
Alkaline and lithium primary cells normally call for electrolytic grade, while zinc-carbon cells are commonly built on chemical grade. State the cell chemistry, MnO2 assay, particle size and impurity limits with the enquiry so the correct grade is quoted.
Is manganese dioxide soluble in water?
It is practically insoluble in water, which is why it works as a granular filter medium and as a solid oxidant rather than a dosing solution. If a water-soluble manganese source is needed, state that in the enquiry so a soluble salt is quoted instead.
Can manganese dioxide be supplied as water-treatment filter media?
Granular manganese dioxide media are used for iron, manganese and hydrogen sulphide removal. Give the flow rate, vessel size, raw water analysis and the particle size range specified by the plant designer, and the media grade can be matched to it.
What details are needed for a manganese dioxide price enquiry?
Provide the grade type, MnO2 or manganese content, mesh or particle size, quantity and delivery location. Mention the end use and any documentation needs so the quotation covers the whole requirement. Supply is subject to applicable requirements.
